Aha! It turns out Cremieux is the r/slatestarcodex poster formerly known as /u/Tr–yPorn0 (slur dashed out), or TP0 for those who don’t even want the slur in dashed-out form. A really persistent race scientist with a habit of (a) misrepresenting the papers he spammed as links (b) misrepresenting himself. He used to run a tiny blog as “Cremieux” when he was claiming to be an economist from Liechtenstein. Then he got pumped by the other race scientists. So I expect this to very much be Racist Fest.
